Appli-cation filed Dctober 20, 1 911. Serial No. 655,743.

To all whom t may concern.'

Be it known that l, ROBERT FRANoIs CoL- noizNE, a citizen of theCommonwealth off man, have invented new and useful lmprovel mentsRelating to Windows, of -which the following is a specification.

By means ofV his invention, whichcomprises the peculiar disposition orlocation ofl a U shaped counter balanceweight, and its attachment to asash `in sucha manner that bothmay be kept apart and yet operatedsimultaneously, provision `is made `for the ready adjustment of thewindow sashes of railway cars or carriages to such a `height as would beallowable by the limitations defined by their structural details, sothat the raising or lowering of the saslies can be easily and quicklyperformed by the occ'u pants of the car or carriage with less trouble`and inconvenience than heretofore.

The invention is devised as a substitute for the catches, stops, andfastenings at present in use for 'supporting and securing the sashes incertain positions, `but which have been found to be liable todislocation, and may therefore become a source of danger to railwaytravelers if the sash should be unexpectedly released from its supportby `the jolting or jarring motions of the carriage.

Referring to the accompanying drawings, which form part of thisspecification. Figure `1 is a vertical sectional elevation of a railwaycar window, showing relative positions of balance weight and sash. Fig.2 is an inside elevation of the car window. showing the sash raised,with U shaped weight in its relative position, one half having casingand louvered shutters in position. the other half stripped of allcovering parts. Fig. 3 is a `horizontal sectional plan, as seen on linea-a of Fig. 2. Fig. a shows, in plan, a detail of the parts of the Ushaped weight, comprising a side guide channel. a suspending attachment,and a fragment of the weight. Fig. 5 is a side elevation of the partsshown in Fig. 4, with fragment of guide channel shown in sectionalelevation. Fig. is a plan of an angularly disposed hanging pulley orsheave, forming the guide and support for suspenders. Fig. 7 is a sideelevation of Fig. 6, Fig. 8 is a plan of a sash hanger. Fig. 9 is avertical sectional elevation on line -b of Fig. 8. Fig. 10 is abackelevation of Figs. 8 and 9, showingl tubular part and securing plate.

The drawings show the invention adapted to the window framing of theAmerican type` of passenger car which is in use on the Australianrailways, and tor which it can be easily and cheaply applied.

The lintel A, the Stiles B, and the sliding sash C, are the existingparts to be utilized incarrying the invention into effect.

'The sash C, which ordinarily slides in the groove D andhas the partingbead E separating it from the louvered sash F sliding in the groove G,eide Fig. 1, has attached to-each of its upper corners the angle strapH, which is fastened with screws in the side and top plates. The saidcorners are hollowed out to"receive the tubular part H', through whichthe suspendingwire iope or `cord I is passed and knotted. In thatposition the secured end l is secreted, and cannot be tampered with.`Each suspending cord is laidover a spindledfgroove sheave l running inits bearing K attached to the foot plate K. The plates, when secured tothe lintel A, provide for each sheave being disposed diagonally7 in thedirection of the angle strap H on the one side, and the pin attachment Lof the counter weight M on the Vc-ther side, with the cord I runningthrough the guide holes K2, 'ticle Fig. 6. To accommodate the counterweight M. and the metal guide channels N in which it slides.

the upper portion of each parting bead F1 has to -he removed. The spaceso created is filled with the channeled pieces N which are secured tothe stiles B. The horn portions M of the weight are placed in aninverted position, and if the weight be detached from the suspendingcords, these parts would rest upon the channel stop ends N. below whichthe remaining part of the stop bead E serves as a guide to the sash whenin its lowermost position. the side iianges of the metal guide channel Nanswering a similar purpose for both the sash C in its upper positionand the louvered sash F.

The counter weight is made U-shaped to obtain the required amount ofmetal to serve as a counterpoise to the sash, and to allow of the hornportions forming side protecting coverings to those parts of the sashwhich would be otherwise exposed when the sash is fully raised, as inFig. 2. The transverse portion is so placed that it is'V only partlyexposed belouT the louvered sash F when it is fully lifted, but it maybe Wholly covered when said louver is slightly lowered.

lWhen sash C is put in any other position than is shown in Figs.` l and2, the couiiter weight is not exposed to view.

The pin attachment L, to which the cord I is secured for supporting thecounter Weight M, hasits head piece pierced at L. It is shaped to iteither Way into lthe cross cavity M2 formed in the weight. The pin partL2, screwed at its extremity, is provided with the clamping nut L3,which can be screwed into position in the opening M3, and tightenedagainst the seating part M.

The obvious advantage of the use of this form of counter balance is,that no 'danger can accrue to the occupants `of the car. Moreover, thesash may be readily placed in any desired position with the minimumamount of force exerted by the occupant, which isnot the case' Withexistingyrailivay car sliding sashes, some of which, I 'am aware, arefitted with recoil springs and compound levers, which are liable todisarrangement. y

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:-

1. Iny a balanced sash Window construction for railway cars, incombination, a frame, a window sash slidably mounted Within the frame,the parting beads of the vertical frame 'Stiles adjacent to the saidsash being cut short" to provide'giiidelWaysfextending downwardly fromthe lintel of the frame, a substantially U-shaped counter-weight mountedfor sliding movement within the frame and having its side horns WorkingWithin the said guideivays and protecting the portions cie the siderails of the sash which are 4situated above the existing portions of thesaid parting beads, and means for connecting the counter-Weightoperatively with y the said sash for relative counterbalancing movement.4

In a balanced sash Window construction for railway .cars, incombination, a frame, a windou7 sash slidably mounted within the frame,a louvered sash mounted similarly in the frame, a substantiallyil-shaped inverted counter-Weight mountedlto slide betiveen the saidsashes, meansgtor connecting the counter-Weight operatively with thesaid Window sash for relative counterbalancing movement, and a stop forthe counter-\veight positioned so that the latter Will have its crossportion partially shielded vby the louvered sash,when the latter is inits highest position, and so that it Will be completely shielded therebyat all other positions.

In testimony whereof I have signed my name to this specification in thepresence `of two subscribing Witnesses. T
